Description

Technical Field

[0001] The utility model relates to a grassland improvement machine, in particular to a natural grassland grass turf cutting machine which uses high-pressure water flow to cut grass. Technical Background

[0002] The causes of grassland degradation can be explained from two aspects, namely natural causes and human causes, and natural causes are particularly important. The method of restoring degraded grassland is to take a series of agricultural technical measures without changing the original vegetation and soil. One of the main measures is to cut the turf to improve soil aeration, cut roots and loosen the soil, break up the soil and increase the contact surface with the air, so that oxygen can enter the soil and create favorable conditions for the activities of aerobic microorganisms. Studies have shown that a dense grass layer will form on the aboveground part in the second year of improvement, and the yield will generally increase by 30%-50%, or even more than double.

[0003] At present, mature machines include deep tillage and rejuvenation machines. The roots of the grassland are cut without destroying or less destroying the original vegetation of the grassland to improve soil ventilation, soil permeability and soil fertility. However, the shortcomings of these machines are that, first, the turf is easily lifted, causing grassland desertification; second, it consumes a lot of power and requires a high-horsepower tractor to operate; third, there is a lack of follow-up operation machinery. After the turf is cut, irrigation, fertilization and reseeding are required immediately, or before the rain comes, so as to replenish water in time. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a high-pressure water flow turf-breaking and root-cutting machine, which can be matched with medium-sized and above tractors, can achieve the effect of timely water replenishment after scratching the turf, cut the turf with small gaps, does not turn the turf outwards, does not damage the grassland structure, and meets the technical requirements of improving natural grassland agriculture.

[0005] The technical problem to be solved by the utility model is achieved by the following structure: a high-pressure water flow grass cutting and root cutting machine, the structure includes a water tank, a water tank bracket, a main frame, a suspension frame, a main gearbox, a high-pressure water supply system, a support frame, and walking wheels.

[0006] The water tank is installed on the main frame through a water tank bracket, and its function is to contain clean water or mixed water with water-retaining and fertilizer-retaining agents and other organic liquid fertilizers. Its bottom is connected to a low-pressure water pipe.

[0007] The main gearbox is installed in front of the main frame and transmits power through the tractor power output shaft and the spline shaft. A universal transmission shaft is installed on the side of the main gearbox, and the main pulley transmission shaft is installed on the main frame through a bearing seat and connected to the universal transmission shaft. A main pulley is installed on one side of the main pulley transmission shaft. The main pulley is connected to the passive pulley through a transmission belt and transmits power to the passive pulley. The passive pulley is connected to the high-pressure water pump through the passive pulley shaft and drives the high-pressure water pump to operate.

[0008] The high-pressure water supply system includes a water tank, a water purifier, a high-pressure water pump, a low-pressure water pipe, a high-pressure water pipe, a distribution valve, and a high-pressure water nozzle. The function is to pressurize the low-pressure water flow into a high-pressure water flow, and the pressure is 100bar-110bar, and the flow rate is 23-25L / min. One end of the low-pressure water pipe is connected to the low-pressure water inlet pipe joint of the water purifier; the other end is connected to the bottom of the water tank. A water supply valve is installed in the middle of the low-pressure water pipe. One end of another low-pressure water pipe is connected to the low-pressure water outlet pipe joint of the water purifier; the other end is connected to the high-pressure water pump. A low-pressure water meter is installed in the middle of the low-pressure water pipe to monitor the pressure of the low-pressure water pipe at any time to ensure water supply. A high-pressure water meter is installed on the upper part of the high-pressure water pump to monitor the pressure of the high-pressure water pipe at any time to ensure that the working pressure required for water outlet is reached. One end of the high-pressure water pipe is connected to the water outlet of the high-pressure water pump; the other end is connected to the distribution valve. The distribution valve is used to send the high-pressure water flow to the high-pressure water pipe branch pipes respectively. A high-pressure water nozzle is arranged at one end of the high-pressure water pipe branch pipeline.

[0009] The high-pressure water nozzle is used to spray high-pressure water into the turf, and the turf and grass roots are continuously cut as the machine moves forward. The high-pressure water nozzle is made of stainless steel, and its interior is threaded, which is convenient for connection with the high-pressure water pipe. A spray hole is processed inside the front outlet, and its spray hole diameter is 2mm-3mm and its length is 8mm-10mm. When the high-pressure water nozzle is working, the optimal height from the ground is 30mm-50mm.

[0010] The nozzle bracket is made of angle steel and its function is to fix the high-pressure water nozzle. Two angle steel connecting plates are welded in the middle, and the other end of the angle steel connecting plate is connected to the round tube bracket through a U-shaped clamp.

[0011] The two ends of the round tube bracket are connected to the upper end of the movable bracket, and the lower end of the movable bracket is connected to the main frame through a pin shaft and can rotate around the pin shaft. The function of the round tube bracket is to control the height of the nozzle bracket and the high-pressure water nozzle from the ground. A lifting cylinder is also installed under the movable bracket. The height of the nozzle bracket and the high-pressure water nozzle from the ground can be manually operated at any time.

[0012] A sewage outlet valve is arranged at one side below the water purifier, and its function is to remove the sundries in the water and ensure that the high-pressure water nozzle is not blocked by sewage.

[0013] The support frame is installed at the front lower part of the main frame, and its function is to support the machine tool when the machine tool is not in operation.

[0014] The advantages of this high-pressure water-flow turf-scraping and root-cutting machine are: 1. It can simultaneously complete the turf-scratching, grass-root-cutting, and soil-loosening processes, with a depth of up to 200-250mm, and has a significant effect on improving natural grasslands. 2. This machine can only open a 20-30mm wide gap in the grassland without turning over the turf or damaging the grassland. It can also inject water into the turf gap to increase humidity. 3. By adding a sowing and fertilizing mechanism to this machine, it can also perform the combined operations of sod-scratching, grass-root-cutting, sowing and fertilizing.
